NUARL / NOE-SV

NUARL Overture is a universal type Hi-Res earphone that is like a custom IEM that allows you to customize the sound based on NUARL's proprietary technology, as well as the volume of the low range and the localization of the sound image, as well as the fit.

■NUARL's unique single full-range dynamic driver
Equipped with a unique ""NUARL DRIVER [N10]v6"" that combines a φ10mm DLC (diamond-like carbon) diaphragm with a 7N grade (99.99999% purity) OCC (single crystal high purity oxygen-free copper wire) voice coil.
The combination of the strongest grade neodymium magnets placed both inside and outside the voice coil with a powerful dual magnet magnetic circuit produces high-definition yet rich sound.

■Dual Chamber Driver Modules
Equipped with a driver module with a dual chamber structure that closes off the front and rear of the driver and has two independent air chambers.
Reproduces the volume of low frequencies regardless of the size of the housing.

■NUARL Phase Guide
Equipped with a unique 3D printed NUARL Phase Guide in the air chamber between the front of the driver and the nozzle.
By suppressing phase interference in the high range and achieving both low distortion and efficiency, we have achieved a smooth high-pitched sound.

■Hybrid HDSS
Adopts the world's first hybrid HDSS with two 3rd generation ETL acoustic modules installed in the driver's rear chamber and one in the front chamber.
It prevents distortion at high volumes and absorbs incidental sounds from the material, reproducing a clear and natural sound spread across the entire band with a three-dimensional effect.

■Location and volume can be selected
Comes with two types of 4-level tone nozzles, long and short, that can adjust only the bass below 500Hz in 2dB increments.
It is possible to select not only the volume of the reproduced sound, but also the spread and localization of the sound.

■Stainless steel is used for the housing body.
The housing is made of stainless steel with excellent rigidity.
By using 5-axis CNC cutting to create a combination of complex curves that cannot be achieved with casting or forging, we have created a unique design that suppresses resonance inside the housing and is easy to install.

■Thorough commitment to sound quality
The driver is aged for 100 hours before installation to stabilize the sound quality.
Brass is used as the material for the nozzle part, and the resonance points are dispersed by changing the housing and material.
For internal wiring and cable connections, 20% silver-containing Pb-free SnAgCu solder made in Japan is used.
The cable has a balanced stereo connection specification that uses a φ4.4mm gold-plated 5-pole plug and a 7N OCC 0.06mm/7x7 8-core silver-plated copper wire, and is compatible with re-cabling using Pentaconn Ear.
The φ3.5mm unbalanced ⇔ φ4.4mm balanced conversion cable also uses 7N OCC 8-core silver-plated copper wire.

■3 types of unique antibacterial earpieces included
Three types of earpieces are included: ``Block Ear+7'', a silicone earpiece that provides both a comfortable fit and sound insulation, ``Block Ear+6N'', which has the same structure and shape but has a 1mm shorter axis, and ``Magic Ear+9'', which uses low-repulsion foam to improve sound insulation.
You can optimize the fit and sound insulation to suit your preferences.
